Description

用於反轉在一圓針織機之一管狀針織物的方法及裝置Method and device for reversing a tubular knitted fabric of a circular knitting machine

本發明關於針織機及裝置的改良。更特定言之，本發明關於一種用於反轉由針筒生產之管狀針織物（諸如短襪或長襪）以便閉合管狀針織物的縫頭端之裝置。如所屬領域中通常理解，「反轉管狀針織物」」意謂將管狀製品自裏至外翻轉，使得外表面變成內表面且內表面變成外表面。The present invention relates to the improvement of knitting machines and devices. More specifically, the present invention relates to a device for reversing a tubular knitted fabric (such as socks or stockings) produced by a needle cylinder to close the seam end of the tubular knitted fabric. As commonly understood in the art, "reversed tubular knitted fabric" means turning the tubular article from the inside to the outside, so that the outer surface becomes the inner surface and the inner surface becomes the outer surface.

管狀針織物，諸如短襪或長襪，通常在圓針織機上製造，該圓針織機具備與針盤共同起作用之單個針筒，或具備兩個同軸且疊加的針筒。針織程序在管狀針織物之一端開始，且在管狀針織物之第二端結束最後一圈線圈的編織而終止。在一些圓針織機中，在其上生產之管狀針織物具有開放的縫頭，該縫頭通常為由針織機之針形成之管狀針織物的最後端且為開放的。管狀針織物之開放縫頭隨後藉由在針筒附近配置之閉合機器中進行縫合或連結而閉合。Tubular knitted fabrics, such as socks or stockings, are usually manufactured on circular knitting machines that have a single needle cylinder that works with a dial, or two coaxial and superimposed needle cylinders. The knitting process starts at one end of the tubular knitted fabric, and ends at the second end of the tubular knitted fabric by knitting the last loop. In some circular knitting machines, the tubular knitted fabric produced thereon has an open seam, which is usually the last end of the tubular knitted fabric formed by the needles of the knitting machine and is open. The open seam of the tubular knitted fabric is then closed by sewing or joining in a closing machine arranged near the needle cylinder.

為了執行連結或縫合，應反轉管狀針織物，亦即自裏至外翻轉。已開發出用於反轉管狀針織物的若干裝置。舉例而言，EP2250307、US9562307、US10145043、EP2961876、EP2946034、WO2002070801、WO2017080890、WO2008028575中揭示用於反轉管狀針織物之裝置。In order to perform joining or stitching, the tubular knitted fabric should be reversed, that is, from the inside to the outside. Several devices have been developed for reversing tubular knitted fabrics. For example, EP2250307, US9562307, US10145043, EP2961876, EP2946034, WO2002070801, WO2017080890, WO2008028575 disclose devices for reversing tubular knitted fabrics.

處置管狀針織物，尤其細規格的女性長襪，可能會損壞該製品並導致廢品。損壞尤其可能出現在反轉短襪或長襪之階段。謹慎地處置管狀針織物之裝置及方法在所屬領域中將為受歡迎的且尤其有用。Disposal of tubular knitted fabrics, especially thin stockings for women, may damage the product and cause waste. Damage may especially occur at the stage of reversing socks or stockings. Devices and methods for the careful handling of tubular knitted fabrics will be popular and especially useful in the art.

又，反轉具有相當大長度的管狀針織物係耗時的且可涉及製品的額外處置，從而可增加損壞製品並產生廢品之風險。提供能夠容易地反轉長管狀針織物之裝置及方法將為有益的。In addition, reversing the tubular knitted fabric with a considerable length is time-consuming and may involve additional disposal of the product, thereby increasing the risk of damaging the product and generating waste. It would be beneficial to provide a device and method capable of easily reversing long tubular knitted fabrics.

本文中所揭示之主題係關於反轉裝置及方法之改良，其旨在減輕或解決當前領域之裝置及方法之缺點及限制中之一或多者。The subject disclosed herein is about the improvement of the inversion device and method, which aims to alleviate or solve one or more of the shortcomings and limitations of the devices and methods in the current field.

雖然描述係指較佳具體實例，其中恢復裝置與用於製造之管狀針織物（諸如短襪及長襪）之包括縫頭閉合台或機器之針織機組合，但每當管狀製品（尤其具有其中之至少一者為開放的第一端及第二端之柔性及柔順製品）必須被自裏至外翻轉，亦即必須被反轉時，本文中所揭示之方法及裝置亦可用於不同內容背景中。Although the description refers to a preferred specific example in which the recovery device is combined with a knitting machine including a seam closing table or machine for the manufacture of tubular knitted fabrics (such as socks and stockings), whenever a tubular product (especially having a At least one of which is an open first end and a flexible and compliant product at the second end) must be turned from the inside to the outside, that is, when it must be reversed, the method and device disclosed in this article can also be used in different content backgrounds in.

根據一個態樣，揭示一種方法，其中該管狀針織物由拾取裝置接合以便藉由其端部自該拾取裝置懸置。該管狀針織物經引入反轉管中，其中該管狀針織物之端部自該拾取裝置懸置。反轉管軸向地移動通過拾取裝置以便藉由其上端突出在拾取裝置上方。反轉管在上部位置與下部位置之間往復地上下移動，在兩個位置中，反轉管之上端均位於拾取裝置上方。在往復移動期間，反轉管與頂部夾持裝置及底部夾持裝置共同起作用，該頂部夾持裝置及該底部夾持裝置抵靠該反轉管選擇性地夾住該管狀針織物並且釋放該管狀針織物，使得該管狀針織物自該反轉管之內部被牽引至其外表面上。重複該往復運動足夠數目次，直至管狀針織物完全在反轉管之外表面上翻轉為止。According to one aspect, a method is disclosed in which the tubular knitted fabric is joined by a pickup device so as to be suspended from the pickup device by its end. The tubular knitted fabric is introduced into the reversing tube, wherein the end of the tubular knitted fabric is suspended from the pickup device. The reversing tube moves axially through the pick-up device so as to protrude above the pick-up device by its upper end. The reversing tube moves up and down between the upper position and the lower position. In both positions, the upper end of the reversing tube is located above the picking device. During the reciprocating movement, the reversing tube works together with the top clamping device and the bottom clamping device. The top clamping device and the bottom clamping device selectively clamp the tubular knitted fabric against the reversing tube and release The tubular knitted fabric enables the tubular knitted fabric to be drawn from the inside of the reversing tube to its outer surface. Repeat this reciprocating motion a sufficient number of times until the tubular knitted fabric is completely turned over on the outer surface of the reversing tube.

根據較佳具體實例，本文中揭示一種用於反轉管狀針織物之方法，其包含按順序執行之以下步驟。管狀針織物之第一端藉助於拾取裝置之複數個環狀地配置之拾取部件接合，使得該管狀針織物藉由其第二端自該拾取裝置懸置。反轉管及拾取裝置接著以大約同軸位置配置，其中反轉管配置在拾取裝置下方。管狀針織物之第二端及管狀針織物自該拾取裝置向下懸置之部分藉由反轉管之上端經引入反轉管中。According to a preferred embodiment, a method for reversing a tubular knitted fabric is disclosed herein, which includes the following steps performed in sequence. The first end of the tubular knitted fabric is joined by means of a plurality of ring-shaped picking members of the picking device, so that the tubular knitted fabric is suspended from the picking device by its second end. The reversing tube and the pick-up device are then arranged in approximately coaxial positions, where the reversing pipe is arranged below the pick-up device. The second end of the tubular knitted fabric and the downwardly suspended part of the tubular knitted fabric from the pick-up device are introduced into the inverted tube through the upper end of the inverted tube.

隨後，反轉管之上端向上移動通過拾取裝置並移動朝向拾取裝置上方之第一豎直位置。反轉管之上端移動通過接合管狀針織物之第一端之拾取裝置使得管狀針織物翻轉至反轉管側壁之外表面上。在此步驟中，可僅獲得部分翻轉，同時管狀針織物之一部分可保持在反轉管內部。此情形在管狀針織物相較於反轉管之延伸部分及其向上衝程之延伸部分較長之情況下尤其如此。Subsequently, the upper end of the reversing tube moves upward through the pickup device and moves toward the first vertical position above the pickup device. The upper end of the reversing tube moves through a pickup device that engages the first end of the tubular knitted fabric to turn the tubular knitted fabric onto the outer surface of the side wall of the reversing tube. In this step, only partial inversion can be obtained, while a part of the tubular knitted fabric can be kept inside the inversion tube. This is especially true when the tubular knitted fabric is longer than the extension of the reversing tube and its upward stroke.

若管狀針織物尚未被完全翻轉，亦即自裏至外被反轉，則在向上衝程結束時，管狀針織物被夾在反轉管之上端與頂部夾持裝置之間。隨後，反轉管之上端及頂部夾持裝置自第一豎直位置朝向低於第一豎直位置之第二豎直位置向下移動，亦即配置於第一豎直位置與拾取裝置之環狀地配置之拾取部件之間。在管狀針織物維持被夾在上部夾持裝置與反轉管之上端之間的同時較佳地執行此移動。If the tubular knitted fabric has not been completely turned over, that is, reversed from the inside to the outside, at the end of the upward stroke, the tubular knitted fabric is clamped between the upper end of the reversing tube and the top clamping device. Subsequently, the upper end and the top clamping device of the reversing tube move downward from the first vertical position toward the second vertical position lower than the first vertical position, that is, the ring that is arranged in the first vertical position and the picking device Between the pick-up parts arranged in a shapely manner. This movement is preferably performed while the tubular knitted fabric remains clamped between the upper clamping device and the upper end of the reversing tube.

下一步驟提供藉助於底部夾持裝置而抵靠反轉管之側壁的外表面夾住管狀針織物，且頂部夾持裝置自反轉管移開並且朝向第一豎直位置向後移動。當反轉管處於第二豎直位置時，底部夾持裝置在拾取裝置附近配置，亦即配置在拾取裝置與反轉管之上端的位置之間。底部夾持裝置之位置使得在拾取裝置與底部夾持裝置之間設置足夠距離。此係尤其有益的，此係由於以此方式在反轉管自第一豎直位置至第二豎直位置之向下移動期間，在反轉管的先前提昇衝程中自反轉管之內部被牽引的管狀針織物在底部夾持裝置下方圍繞反轉管之外表面被聚集。一旦底部夾持裝置抵靠反轉管夾住管狀針織物並且反轉管再次朝向第一豎直位置被提昇，則在拾取部件與底部夾持裝置之間被翻轉並聚集的管狀針織物之長度在其向上移動期間將不由反轉管向上牽引。The next step provides clamping the tubular knitted fabric against the outer surface of the side wall of the inverted tube by means of the bottom clamping device, and the top clamping device is moved away from the inverted tube and moved backward toward the first vertical position. When the reversing tube is in the second vertical position, the bottom clamping device is arranged near the picking device, that is, between the picking device and the position of the upper end of the reversing tube. The position of the bottom clamping device is such that a sufficient distance is provided between the pickup device and the bottom clamping device. This is particularly beneficial because in this way, during the downward movement of the reversing tube from the first vertical position to the second vertical position, the interior of the reversing tube is removed from the inside of the reversing tube during the previous lifting stroke The drawn tubular knitted fabric is gathered around the outer surface of the reversing tube under the bottom clamping device. Once the bottom clamping device clamps the tubular knitted fabric against the reversing tube and the reversing tube is lifted again toward the first vertical position, the length of the tubular knitted fabric that is flipped and gathered between the picking member and the bottom clamping device During its upward movement, it will not be pulled upward by the reversing tube.

在以下步驟中，一旦頂部夾持裝置脫離反轉管，則反轉管再次朝向第一豎直位置向上移動，且向上移動使得管狀針織物進一步翻轉至反轉管之側壁的外表面上。In the following steps, once the top clamping device is detached from the reversing tube, the reversing tube moves upward again toward the first vertical position, and moves upward so that the tubular knitted fabric is further turned over to the outer surface of the side wall of the reversing tube.

當反轉管處於第二豎直位置時仍在反轉管內部之管狀針織物的至少一部分自反轉管的內部撤出且經翻轉在其外表面上，此係由於管狀針織物之已經反轉的部分由於底部夾持裝置之夾住動作而被阻止由向上移動之反轉管向上牽引。底部夾持裝置之摩擦係數高於反轉管之外表面的摩擦係數，使得當反轉管向上移動時，管狀針織物係由高摩擦底部夾持裝置固持。已經在反轉管之先前向下衝程期間在底部夾持裝置與拾取裝置之間聚集的管狀針織物之已經反轉的部分係由底部夾持裝置固持並且被阻止由反轉管向上牽引。When the reversing tube is in the second vertical position, at least a part of the tubular knitted fabric still inside the reversing tube is withdrawn from the inside of the reversing tube and turned on its outer surface, because the tubular knitted fabric has been reversed The rotating part is prevented from being pulled upward by the upwardly moving reversing tube due to the clamping action of the bottom clamping device. The friction coefficient of the bottom clamping device is higher than that of the outer surface of the reversing tube, so that when the reversing tube moves upward, the tubular knitted fabric is held by the high friction bottom clamping device. The already inverted part of the tubular knitted fabric that has gathered between the bottom clamping device and the pick-up device during the previous downward stroke of the inverting tube is held by the bottom clamping device and prevented from being pulled upward by the inverting tube.

必要時，上文所描述的反轉管之向下及向上移動視需要被重複一次或多次，直至管狀針織物在反轉管之側壁的外表面上完全自裏至外反轉且反轉管之上端脫離管狀針織物為止。If necessary, the downward and upward movement of the reversing tube described above is repeated one or more times as necessary, until the tubular knitted fabric is completely reversed and reversed from the inside to the outside on the outer surface of the side wall of the reversing tube The upper end of the tube is separated from the tubular knitted fabric.

根據一些具體實例，首次將反轉管之上端移動通過拾取裝置並將其朝向第一豎直位置移動之步驟可進一步包含以下步驟：將反轉管之上端移動至環狀地配置之拾取部件上方的一位置；藉由底部夾持裝置抵靠反轉管之側壁的外表面夾住管狀針織物；及進一步朝向第一豎直位置移動反轉管。According to some specific examples, the step of moving the upper end of the reversing tube through the picking device for the first time and moving it toward the first vertical position may further include the following step: moving the upper end of the reversing tube above the ring-shaped picking member A position; clamp the tubular knitted fabric against the outer surface of the side wall of the reversing tube by the bottom clamping device; and further move the reversing tube toward the first vertical position.

根據另一態樣，揭示一種用於反轉管狀針織物之裝置。該裝置包含拾取裝置，其可包括經調適以接合管狀針織物之第一端的複數個環狀地配置之拾取部件。該裝置進一步包含反轉管，其具有上端、下端及自上端延伸至下端之側壁。反轉管及拾取裝置經調適以配置於大約同軸的位置中。此外，反轉管經調適以在拾取裝置下方自下部位置提昇，使得反轉管之上端朝向在拾取裝置上方之其第一上部豎直位置移動通過拾取裝置。According to another aspect, a device for reversing tubular knitted fabric is disclosed. The device includes a pickup device, which may include a plurality of ring-shaped pickup members adapted to engage the first end of the tubular knitted fabric. The device further includes an inverted tube having an upper end, a lower end, and a side wall extending from the upper end to the lower end. The reversing tube and the pick-up device are adapted to be arranged in approximately coaxial positions. In addition, the reversing tube is adapted to lift from the lower position below the picking device, so that the upper end of the reversing pipe moves through the picking device toward its first upper vertical position above the picking device.

如本文中所使用，「大約同軸的位置」為允許反轉管穿過拾取裝置之此位置。兩個部件不需要完全地同軸。重要的為反轉管可與其上端一起移動通過拾取裝置以發起翻轉程序。As used herein, the "approximately coaxial position" is the position that allows the reversing tube to pass through the pickup device. The two parts need not be completely coaxial. It is important that the reversing tube can be moved with its upper end through the pick-up device to initiate the reversing procedure.

該裝置進一步包括頂部夾持裝置，其經調適以抵靠反轉管之上端在拾取裝置上方之上部豎直位置中夾住管狀針織物並連同反轉管一起在上部豎直位置朝向第二下部豎直位置之間移動，該下部豎直位置在拾取裝置上方。該裝置亦包括底部夾持裝置，其經配置於第一上部位置與拾取裝置之間且經調適以在夾住位置與脫離反轉管之位置之間選擇性地移動，在該夾住位置中，底部夾持裝置抵靠反轉管之側壁夾住管狀針織物。The device further includes a top clamping device adapted to clamp the tubular knitted fabric in the upper vertical position above the picking device against the upper end of the inverted tube and to the second lower part in the upper vertical position together with the inverted tube Move between vertical positions, the lower vertical position above the picking device. The device also includes a bottom clamping device, which is arranged between the first upper position and the pick-up device and is adapted to move selectively between a clamping position and a position free from the inverted tube, in the clamping position , The bottom clamping device clamps the tubular knitted fabric against the side wall of the reversing tube.

在此參考附圖描述該方法及該裝置之其他特徵及具體實例。The other features and specific examples of the method and the device are described with reference to the accompanying drawings.

在以下描述中，結合用於閉合例如短襪或長襪之管狀針織物之端部（例如縫頭端）之圓針織機及連結或縫合機器來描述反轉方法及裝置。儘管如此，針織的所屬技術領域中具有通常知識者將自以下描述理解，例如在經反轉管狀針織物不經受縫合或連結動作及/或其中管狀針織物不被直接自圓針織機拾取的狀況下，本發明之新穎及有用態樣亦用於不同配置中。In the following description, the reversal method and device are described in conjunction with a circular knitting machine and a joining or sewing machine for closing the ends (such as the seam end) of tubular knitted fabrics such as socks or stockings. Nevertheless, those with ordinary knowledge in the technical field of knitting will understand from the following description, for example, in a situation where the reversed tubular knitted fabric is not subjected to stitching or joining actions and/or the tubular knitted fabric is not picked up directly from the circular knitting machine Next, the novel and useful aspects of the present invention are also used in different configurations.

現在轉而參看圖式，圖1說明包括圓針織機3、拾取裝置5及縫合或連結機器或台7之單元1的立體正投影視圖。由於管狀針織物之縫頭端可藉由縫合或連結或任何其他合適的閉合操作來閉合，因此機器7將在此僅被稱作閉合機器或閉合台，且由閉合機器7執行之相關操作將亦僅被稱作管狀針織物之縫頭端的「閉合」或「封閉」。Turning now to the drawings, FIG. 1 illustrates a three-dimensional orthographic view of a unit 1 including a circular knitting machine 3, a pick-up device 5, and a sewing or joining machine or table 7. Since the seam end of the tubular knitted fabric can be closed by sewing or joining or any other suitable closing operation, the machine 7 will be referred to herein as a closing machine or a closing table, and the related operations performed by the closing machine 7 will be It is also only called the "closed" or "closed" of the seam end of the tubular knitted fabric.

圓針織機3包括圓形針床，例如針筒9。在一些具體實例中，拾取裝置5可圍繞豎直軸線5A樞轉，以自其中拾取裝置與針筒9同軸之拾取位置移動至其中拾取裝置5與閉合機器7及共同標記為11之反轉配置共同起作用之反轉及閉合位置。The circular knitting machine 3 includes a circular needle bed, such as a needle cylinder 9. In some specific examples, the pick-up device 5 can pivot about the vertical axis 5A to move from the pick-up position where the pick-up device is coaxial with the syringe 9 to the inverted configuration where the pick-up device 5 and the closing machine 7 are collectively marked as 11 Reverse and closed positions that work together.

將詳細地描述拾取裝置5，此係由於此種類型之裝置為吾人所知。對於關於適於本文中所揭示之單元1之拾取裝置的可能的具體實例之更多細節，可參考例如US10145043、WO2017067801或EP2984220。圖1A作為實例以自底部之立體正投影視圖說明拾取裝置5之具體實例，該拾取裝置包括複數個拾取部件13，其根據拾取部件13之第一半圓形集合13A及拾取部件13之第二組半圓形集合13B配置。更特定言之，拾取部件5包含兩個半圓形冠部12A、12B，在其上提供用於拾取部件13A、13B之支座。拾取部件之兩個半圓形集合中之一者經調適以相對於另一者圍繞直徑軸線B-B樞軸，使得拾取部件之第一及第二半圓形集合可配置於第一共面位置中（圖1A）及第二疊加位置中，其中兩個半圓形集合之拾取部件呈面對面關係。The pickup device 5 will be described in detail because this type of device is known to us. For more details on possible specific examples of the pickup device suitable for the unit 1 disclosed herein, refer to, for example, US10145043, WO2017067801 or EP2984220. FIG. 1A is taken as an example to illustrate a specific example of a pick-up device 5 with a three-dimensional orthographic view from the bottom. The pick-up device includes a plurality of pick-up parts 13, which are based on the first semicircular set 13A of the pick-up parts 13 and the second pick-up part 13 Set of semicircular set 13B configuration. More specifically, the pick-up component 5 includes two semicircular crowns 12A, 12B, on which a support for the pick-up components 13A, 13B is provided.

圖1B說明反轉配置11之擴大，其展示反轉配置之各種組件。參考圖1B且繼續參考圖1，反轉配置11包括反轉管15，其具備根據雙箭頭f15之豎直往復運動。該移動可受致動器14控制。在此具體實例中，致動器14為線性致動器，亦即氣壓缸活塞致動器。然而，可使用其他致動器，例如包含電動馬達之旋轉致動器等等。可提供可移動止動件或鎖16，以限制反轉循環之步驟中之一些中的反轉管15之向下移動，如以後將更詳細描述。Figure 1B illustrates an expansion of the inverted configuration 11, which shows various components of the inverted configuration. With reference to Fig. 1B and with continued reference to Fig. 1, the reversing configuration 11 includes a reversing tube 15 provided with a vertical reciprocating movement according to the double arrow f15. This movement can be controlled by the actuator 14. In this specific example, the actuator 14 is a linear actuator, that is, a pneumatic cylinder piston actuator. However, other actuators can be used, such as rotary actuators including electric motors, and the like. A movable stop or lock 16 may be provided to limit the downward movement of the reversing tube 15 in some of the steps of the reversing cycle, as will be described in more detail later.

反轉配置11進一步包含上部抽吸管17，其實質上與反轉管15同軸且配置於其上方。抽吸管17具備根據雙箭頭f17之往復豎直運動。抽吸管17之豎直移動可受致動器控制，例如線性致動器，諸如氣壓缸活塞致動器，其未詳細說明。用於控制抽吸管17及反轉管15之移動的其他致動器為可能的，例如液壓缸活塞致動器，電動、氣動或液壓旋轉馬達等等。The inversion arrangement 11 further includes an upper suction tube 17 which is substantially coaxial with the inversion tube 15 and arranged above it. The suction pipe 17 has a reciprocating vertical movement according to the double arrow f17. The vertical movement of the suction pipe 17 may be controlled by an actuator, such as a linear actuator, such as a pneumatic cylinder piston actuator, which is not described in detail. Other actuators for controlling the movement of the suction pipe 17 and the reversing pipe 15 are possible, such as hydraulic cylinder piston actuators, electric, pneumatic or hydraulic rotary motors, etc.

在閒置位置中，如圖1及圖1B中所展示，抽吸管17及反轉管15分別配置在水平幾何平面上方及下方，該等水平幾何平面界定其中拾取部件5可圍繞軸線5A旋轉移動（雙箭頭f5，圖1）之空間。此使得能夠在反轉管15與抽吸管17之間引入拾取裝置5。In the idle position, as shown in FIGS. 1 and 1B, the suction tube 17 and the reversing tube 15 are respectively arranged above and below the horizontal geometric planes, which define the pick-up part 5 to move around the axis 5A. (Double arrow f5, Figure 1) space. This makes it possible to introduce the pickup device 5 between the reversal tube 15 and the suction tube 17.

反轉配置11進一步包括用以將與拾取構件5接合之管狀針織物引入至反轉管15中之構件。此等構件可包括機械及/或氣動部件。在本文中所揭示之具體實例中，提供機械部件與氣動部件之組合。更特定言之，用於將管狀針織物引入反轉管15中之構件包含小棒19，其以樞轉方式支撐在托架21上。根據雙箭頭f21之托架21的豎直往復移動可受任何合適的致動器控制。在圖式中所說明之例示性具體實例中，使用無棒或無軸氣壓缸活塞致動器23，其亦形成用於引導托架21之引導件。其他致動器可用於控制托架21之運動。應注意，一般而言，除非不同地規定，否則用於控制機器之各個部件的移位之致動器可選自任何種類的可用的合適致動器，無論本文中所描述的特定致動器之類型及性質如何。小棒19在由托架21支撐之旋轉致動器25的控制下可進一步以樞轉方式圍繞水平軸線移動。用於將短襪引入反轉管15中之構件可進一步包括氣動構件，例如設置在諸如吹氣棒27之吹氣部件上的吹氣噴嘴或一組吹氣噴嘴，其產生噴氣或鼓風，噴氣或鼓風經導向以便促進管狀針織物***在反轉管15中。反轉管中之抽吸可用來代替由噴嘴產生的鼓風或與其組合使用。The reversing arrangement 11 further includes a member for introducing the tubular knitted fabric joined with the pickup member 5 into the reversing tube 15. These components may include mechanical and/or pneumatic components. In the specific examples disclosed herein, a combination of mechanical components and pneumatic components is provided. More specifically, the member for introducing the tubular knitted fabric into the reversing tube 15 includes a small rod 19 which is pivotally supported on the bracket 21. The vertical reciprocating movement of the carriage 21 according to the double arrow f21 can be controlled by any suitable actuator. In the illustrative example illustrated in the drawings, a rodless or shaftless pneumatic cylinder piston actuator 23 is used, which also forms a guide for guiding the bracket 21. Other actuators can be used to control the movement of the carriage 21. It should be noted that in general, unless otherwise specified, the actuators used to control the displacement of the various parts of the machine can be selected from any kind of suitable actuators available, regardless of the specific actuators described herein. What is its type and nature. The small rod 19 can be further moved around a horizontal axis in a pivoting manner under the control of the rotary actuator 25 supported by the bracket 21. The member used to introduce the sock into the reversing tube 15 may further include a pneumatic member, for example, a blowing nozzle or a set of blowing nozzles provided on a blowing part such as a blowing rod 27, which generates a jet or a blast, The air jet or blower is guided to facilitate insertion of the tubular knitted fabric into the reversing tube 15. The suction in the reversing tube can be used in place of or in combination with the blast generated by the nozzle.

在一些具體實例中，圖中未示，吹氣棒27可具備往復豎直移動，以便於管狀針織物S***反轉管15中。在一些具體實例中，吹氣棒27可由實質上水平棒替代，該實質上水平棒不具有吹氣噴嘴並且具備往復豎直移動。In some specific examples, not shown in the figure, the blowing rod 27 may have a reciprocating vertical movement to facilitate the insertion of the tubular knitted fabric S into the reversing tube 15. In some specific examples, the blowing rod 27 may be replaced by a substantially horizontal rod that does not have a blowing nozzle and has a reciprocating vertical movement.

反轉管15具有下端15A及上端15B（圖9中最佳展示）以及在下端15A與上端15B之間延伸的側壁15D。在一些具體實例中側壁15D具有側開口15C，其促進管狀針織物***其中，如以後將更詳細解釋。在一些具體實例中，圖中未示，下部反轉管15亦可具備圍繞水平軸線之樞轉移動以採用使管狀針織物較容易***的位置。The reversal tube 15 has a lower end 15A and an upper end 15B (best shown in FIG. 9) and a side wall 15D extending between the lower end 15A and the upper end 15B. In some specific examples, the side wall 15D has a side opening 15C, which facilitates the insertion of the tubular knitted fabric therein, as will be explained in more detail later. In some specific examples, not shown in the figure, the lower reversing tube 15 may also have a pivotal movement around a horizontal axis to adopt a position where the tubular knitted fabric is easier to insert.

在拾取裝置5可沿著旋轉移動之平面上方，可配置兩個夾持裝置，其與反轉管15共同起作用以便自裏至外反轉管狀針織物。更特定言之，頂部夾持裝置31經調適以根據箭頭f31沿著豎直引導件33移動。另一底部夾持裝置35配置於更低層級處，在頂部夾持裝置31下方並在拾取裝置5上方。底部夾持裝置35可根據雙箭頭f35在水平方向上移動。頂部夾持裝置31及底部夾持裝置35之根據f31及f35的動作可受合適致動器控制，例如無軸或無棒氣壓缸活塞致動器或其他類型之合適致動器。Above the plane where the pickup device 5 can move along the rotation, two clamping devices can be arranged, which work together with the reversing tube 15 to reverse the tubular knitted fabric from the inside to the outside. More specifically, the top clamping device 31 is adapted to move along the vertical guide 33 according to the arrow f31. Another bottom clamping device 35 is arranged at a lower level, below the top clamping device 31 and above the picking device 5. The bottom clamping device 35 can be moved in the horizontal direction according to the double arrow f35. The actions of the top clamping device 31 and the bottom clamping device 35 according to f31 and f35 can be controlled by suitable actuators, such as shaftless or rodless pneumatic cylinder piston actuators or other types of suitable actuators.

繼續參考圖1、圖1A、圖1B，將參考圖2至圖13更詳細地描述反轉循環。反轉循環包含步驟的第一序列（圖2至圖5）以自針筒9移除管狀針織物S並將該製品引入反轉管15中。步驟的第二序列自裏至外反轉管狀針織物S。With continued reference to FIGS. 1, 1A, and 1B, the reversal cycle will be described in more detail with reference to FIGS. 2 to 13. The reversal cycle includes a first sequence of steps (FIGS. 2 to 5) to remove the tubular knitted fabric S from the needle cylinder 9 and introduce the product into the reversal tube 15. The second sequence of steps reverses the tubular knitted fabric S from inside to outside.

在圖2中說明第一序列的第一步驟。針織機3已結束生產管狀針織物S，諸如短襪或長襪。針織程序自彈性貼邊開始且以製品的縫頭結束。在以下描述中，縫頭將被稱作「第一端」，其經閉合、縫合或連結。彈性貼邊將被稱作管狀針織物的「第二端」。在圖2中，管狀針織物S的縫頭已經由拾取裝置5的拾取部件13（在圖1A中詳細展示）接合。拾取裝置仍處於拾取位置，與針筒9同軸。反轉管15處於下部位置。圖2中不可見之抽吸管17處於上部位置。The first step of the first sequence is illustrated in FIG. 2. The knitting machine 3 has finished producing tubular knitted fabrics S, such as socks or stockings. The knitting process starts with the elastic welt and ends with the seam of the product. In the following description, the seam head will be referred to as the "first end", which is closed, stitched or joined. The elastic welt will be called the "second end" of the tubular knitted fabric. In FIG. 2, the seam of the tubular knitted fabric S has been joined by the pickup member 13 of the pickup device 5 (shown in detail in FIG. 1A ). The pickup device is still in the pickup position, coaxial with the syringe 9. The reversal tube 15 is in the lower position. The suction tube 17 not visible in Figure 2 is in the upper position.

拾取裝置5圍繞豎直軸線5A自圖2的位置旋轉至圖3的位置。在圖3中，拾取裝置5定位於反轉管15與抽吸管17之間且實質上與其同軸。在此例示性具體實例中，管狀針織物S尤其長，使得當拾取裝置5處於圖3的位置時，管狀針織物S的第二端仍在針筒9內部。The pickup device 5 rotates around the vertical axis 5A from the position of FIG. 2 to the position of FIG. 3. In Fig. 3, the pickup device 5 is positioned between the reversing tube 15 and the suction tube 17 and is substantially coaxial therewith. In this illustrative specific example, the tubular knitted fabric S is particularly long, so that when the pickup device 5 is in the position of FIG. 3, the second end of the tubular knitted fabric S is still inside the needle cylinder 9.

為了自針筒9完全移除管狀針織物S並且將其下部部分引入反轉管15中，小棒19根據圖4中之箭頭f21向下旋轉及平移。經組合之藉由反轉管15之空氣抽吸與藉由吹氣棒27之空氣吹氣將自拾取裝置5向下懸置之管狀針織物S之一部分引入至反轉管15中，如圖5中所展示。現在，管狀針織物S之開放縫頭端S1由拾取裝置5之拾取部件13接合，而其第二下端S2在反轉管15內部向下自由懸置。In order to completely remove the tubular knitted fabric S from the needle cylinder 9 and introduce its lower part into the reversing tube 15, the small rod 19 rotates and translates downward according to the arrow f21 in FIG. The combined air suction by the reversing tube 15 and the air blowing by the air blowing rod 27 introduce a part of the tubular knitted fabric S suspended downward from the pickup device 5 into the reversing tube 15, as shown in the figure Shown in 5. Now, the open seam end S1 of the tubular knitted fabric S is joined by the pickup member 13 of the pickup device 5, and the second lower end S2 thereof is freely suspended downwards inside the reversing tube 15.

現在執行步驟的以下第二序列以自裏至外反轉管狀針織物S。Now perform the following second sequence of steps to reverse the tubular knitted fabric S from the inside to the outside.

在圖6中，反轉管15根據箭頭f15向上移動，使得反轉管15的上端15B移動通過拾取部件5直至第一上部豎直位置。可在底部夾持裝置35維持不在作用中，亦即與反轉管15保持一定距離時，執行反轉管15的向上衝程。在一替代具體實例中，向上行程可劃分成第一部分衝程及第二部分衝程。在第一部分衝程結束時，反轉管15的上端15B位於拾取裝置5上方，且處於定位底部夾持裝置35之位置，或在該位置上方。底部夾持裝置35抵靠反轉管15的側壁15之外表面啟動並經推動，使得管狀針織物S被夾在底部夾持裝置35與反轉管15之間。當執行向上移動的第二衝程時，反轉管15之光滑的外表面（其可經拋光）在管狀針織物S之內表面上滑動，該管狀針織物藉由摩擦保持附著至底部夾持裝置35。In FIG. 6, the reversing tube 15 moves upward according to the arrow f15, so that the upper end 15B of the reversing tube 15 moves through the picking member 5 to the first upper vertical position. The upward stroke of the reversing tube 15 can be performed when the bottom clamping device 35 is not in operation, that is, when keeping a certain distance from the reversing tube 15. In an alternative embodiment, the upward stroke can be divided into a first partial stroke and a second partial stroke. At the end of the first part of the stroke, the upper end 15B of the reversing tube 15 is located above the pick-up device 5, and is at the position where the bottom clamping device 35 is positioned, or above this position. The bottom clamping device 35 is activated against the outer surface of the side wall 15 of the reversing tube 15 and pushed so that the tubular knitted fabric S is clamped between the bottom clamping device 35 and the reversing tube 15. When the second stroke of the upward movement is performed, the smooth outer surface of the reversing tube 15 (which can be polished) slides on the inner surface of the tubular knitted fabric S, which is kept attached to the bottom clamping device by friction 35.

無論底部夾持裝置35是在作用中抑或閒置，反轉管15之向上移動使得在反轉管15內部之管狀針織物S在其外部經牽拉並在反轉管15之側壁15D的外表面上翻轉。若底部夾持裝置35不在作用中，則在反轉管15外部牽拉管狀針織物S係藉由拾取部件13施加之保持動作確保，該等拾取部件防止藉由摩擦向上牽引管狀針織物S。因此，在此步驟中，管狀針織物S沿著反轉管15之上邊緣滑動並且在反轉筒15外部經逐步地牽拉且圍繞其翻轉。Regardless of whether the bottom clamping device 35 is active or idle, the upward movement of the reversing tube 15 causes the tubular knitted fabric S inside the reversing tube 15 to be drawn on the outside and on the outer surface of the side wall 15D of the reversing tube 15 Flip up. If the bottom clamping device 35 is not in effect, pulling the tubular knitted fabric S outside the reversing tube 15 is ensured by the holding action applied by the picking members 13, which prevent the tubular knitted fabric S from being pulled upward by friction. Therefore, in this step, the tubular knitted fabric S slides along the upper edge of the reversing tube 15 and is gradually pulled outside the reversing cylinder 15 and turned around it.

若一旦反轉管15已達成其上部位置，亦即圖6中所展示之第一豎直位置，則整個管狀針織物已經自反轉管15之內部被牽拉出來且圍繞反轉管15之外表面配置，則反轉程序結束。舉例而言，此可藉助於光電池或發光接收配置被偵測到，該光電池或發光接收配置使用反轉管15之反射外表面。若已完全反轉管狀針織物S，則反轉管15之上端15B不含織物，可以光學方式偵測到該狀況。可使用其他偵測構件，諸如電容構件或與僅為反轉管15之外表面共同起作用之電觸點。Once the reversing tube 15 has reached its upper position, that is, the first vertical position shown in FIG. 6, the entire tubular knitted fabric has been pulled out from the inside of the reversing tube 15 and surrounding the reversing tube 15 If the outer surface is configured, the reversal procedure ends. For example, this can be detected by means of a photocell or a light-emitting receiving configuration that uses the reflective outer surface of the inverted tube 15. If the tubular knitted fabric S has been completely reversed, the upper end 15B of the reversing tube 15 contains no fabric, and this situation can be detected optically. Other detection components can be used, such as capacitive components or electrical contacts that work with only the outer surface of the reversing tube 15.

在其他具體實例中，管狀針織物S之長度可儲存在控制單元之儲存記憶體中。控制單元可經程式化以便基於管狀針織物S的儲存長度判定在反轉管15之第一向上衝程結束時是否已經完全反轉管狀針織物S。In other specific examples, the length of the tubular knitted fabric S may be stored in the storage memory of the control unit. The control unit may be programmed to determine whether the tubular knitted fabric S has been completely reversed at the end of the first upward stroke of the reversing tube 15 based on the storage length of the tubular knitted fabric S.

若管狀針織物S之一部分仍在反轉管15內部，則執行圖7A、圖7B中所展示之另一反轉步驟。兩個圖說明該裝置的兩個放大部分。更特定言之，圖7A說明圍繞反轉管15之上端15B的區域，而圖7B說明拾取部件下方之區域。如圖7A中所展示，已經啟動頂部夾持裝置31使得管狀針織物S被夾在頂部夾持裝置31與反轉管15之上端15B之間。一旦頂部夾持裝置31抵靠反轉管15按壓管狀針織物S並將其安全地固持該頂部夾持裝置與該反轉管，則反轉管15及頂部夾持裝置15可根據圖7A中之箭頭f31及f15同時向下移動。底部夾持裝置35脫離反轉管15及圍繞其配置之管狀針織物S，使得管狀針織物S可由向下移動之反轉管15牽引而不干擾底部夾持裝置35。拾取部件13之環形配置與反轉管15之外表面之間的間隙足夠小以防止管狀針織物S被反轉管15向下牽引。If a part of the tubular knitted fabric S is still inside the reversing tube 15, another reversing step shown in FIGS. 7A and 7B is performed. The two figures illustrate two enlarged parts of the device. More specifically, FIG. 7A illustrates the area surrounding the upper end 15B of the reversing tube 15, and FIG. 7B illustrates the area below the pickup member. As shown in FIG. 7A, the top clamping device 31 has been activated so that the tubular knitted fabric S is clamped between the top clamping device 31 and the upper end 15B of the reversing tube 15. Once the top clamping device 31 presses the tubular knitted fabric S against the reversing tube 15 and securely holds the top clamping device and the reversing tube, the reversing tube 15 and the top clamping device 15 can be as shown in FIG. 7A The arrows f31 and f15 move down at the same time. The bottom clamping device 35 is separated from the reversing tube 15 and the tubular knitted fabric S arranged around it, so that the tubular knitted fabric S can be pulled by the reversing tube 15 moving downward without disturbing the bottom clamping device 35. The gap between the annular configuration of the picking member 13 and the outer surface of the reversing tube 15 is small enough to prevent the tubular knitted fabric S from being pulled downward by the reversing tube 15.

反轉管15之下降運動在其上端15B移動經過底部夾持裝置35之前結束。該底部夾持裝置經置放在距拾取裝置15上方的一距離處，使得管狀針織物S之在反轉管15的外表面上的至少一部分將圍繞向下移動之反轉管15聚集在底部夾持裝置35與拾取裝置5之間。The descending movement of the reversing tube 15 ends before its upper end 15B moves past the bottom clamping device 35. The bottom clamping device is placed at a distance above the picking device 15 so that at least a part of the tubular knitted fabric S on the outer surface of the reversing tube 15 will gather at the bottom around the reversing tube 15 moving downward Between the clamping device 35 and the pickup device 5.

反轉管15之下降衝程之結束可由可移動止動件16界定。圖7B說明在此部分下降衝程結束時的反轉管15之下部部分。使用可移動止動件16避免需要準確地控制移動反轉管15之致動器。因此，簡單的氣缸活塞致動器可用於控制反轉管15的上下移動。The end of the descending stroke of the reversing tube 15 can be defined by the movable stop 16. Fig. 7B illustrates the lower part of the reversing tube 15 at the end of this partial descending stroke. The use of the movable stop 16 avoids the need to accurately control the actuator that moves the reversing tube 15. Therefore, a simple cylinder piston actuator can be used to control the up and down movement of the reversing tube 15.

在其他具體實例中，反轉管15之移動可受較複雜的致動器控制，諸如以電子方式受控制之電動馬達。在又其他具體實例中，與活塞氣缸致動器組合之磁性控制裝置可用於執行所需長度的衝程。可以電子方式控制下降衝程之結束。In other specific examples, the movement of the reversing tube 15 may be controlled by a more complex actuator, such as an electric motor controlled electronically. In still other specific examples, a magnetic control device combined with a piston cylinder actuator can be used to perform a stroke of a desired length. The end of the descending stroke can be controlled electronically.

如圖7A中所展示，在反轉管15之向下移動結束時，管狀針織物S之一部分在拾取裝置5與底部夾持裝置35之間堆積成圍繞反轉管15之外表面形成褶皺SC。如上文所提及，對於裝置之高效操作，底部夾持裝置35位於由反轉管15之上端15B到達之第一豎直位置與拾取裝置5之間的中間位置中。底部夾持裝置35與拾取裝置5之間的距離使得管狀針織物S可在反轉管15之向下移動期間至少部分地在底部夾持裝置35與拾取裝置5之間聚集。As shown in FIG. 7A, at the end of the downward movement of the reversing tube 15, a part of the tubular knitted fabric S is piled up between the picking device 5 and the bottom clamping device 35 to form a wrinkle SC around the outer surface of the reversing tube 15 . As mentioned above, for the efficient operation of the device, the bottom clamping device 35 is located in an intermediate position between the first vertical position reached by the upper end 15B of the reversing tube 15 and the picking device 5. The distance between the bottom clamping device 35 and the pickup device 5 is such that the tubular knitted fabric S can be at least partially gathered between the bottom clamping device 35 and the pickup device 5 during the downward movement of the reversing tube 15.

在下一步驟中（圖8），頂部夾持裝置31移離反轉管15之上端15B，以便允許執行下一翻轉步驟。藉由自反轉管15之上端15B移開頂部夾持裝置31，管狀針織物S變得自由地被進一步自反轉管15拉出。如圖8中所展示，頂部夾持裝置31可向後（箭頭f31）移動至其上部豎直位置。In the next step (Figure 8), the top clamping device 31 is moved away from the upper end 15B of the reversing tube 15 to allow the next reversing step to be performed. By removing the top clamping device 31 from the upper end 15B of the reversing tube 15, the tubular knitted fabric S becomes free to be further pulled out from the reversing tube 15. As shown in Fig. 8, the top clamping device 31 can be moved backward (arrow f31) to its upper vertical position.

啟動底部夾持裝置35，使得管狀針織物S被夾持，亦即被夾在底部夾持裝置35與反轉管15之外表面之間。該反轉管可再次朝向上部第一豎直位置向上移動，如圖8中之箭頭f15所展示。在此移動期間，管狀針織物之另一部分自反轉管15之內部被拉出。實際上，在底部夾持裝置35下方聚集（參見褶皺，圖7A、圖8、圖9）之已經翻轉的管狀針織物S之部分由於底部夾持裝置之動作被阻止由向上移動之反轉管15牽引，該底部夾持裝置之摩擦係數高於反轉管15之外表面的摩擦係數。The bottom clamping device 35 is activated, so that the tubular knitted fabric S is clamped, that is, between the bottom clamping device 35 and the outer surface of the reversing tube 15. The reversing tube can again move upward toward the upper first vertical position, as shown by arrow f15 in FIG. 8. During this movement, another part of the tubular knitted fabric is pulled out from the inside of the reversing tube 15. In fact, the portion of the tubular knitted fabric S that has been turned over that is gathered under the bottom clamping device 35 (see folds, Figures 7A, 8 and 9) is prevented by the upwardly moving reverse tube due to the action of the bottom clamping device 15 traction, the friction coefficient of the bottom clamping device is higher than the friction coefficient of the outer surface of the reversing tube 15.

在反轉管15之此進一步向上衝程結束時，管狀針織物S可完全在反轉管15外部，如圖9中所展示。反轉管15之上端15B在此狀況下沒有管狀針織物S，可以光學方式或以任何其他合適方式偵測到該狀況。舉例而言，在一些具體實例中，衝程之數目可基於待處置的管狀針織物S之長度在開始時經程式化。此可簡化機器之結構及控制。因而結束反轉或反轉程序。At the end of this further upward stroke of the reversing tube 15, the tubular knitted fabric S may be completely outside the reversing tube 15, as shown in FIG. 9. The upper end 15B of the reversing tube 15 has no tubular knitted fabric S in this condition, and this condition can be detected optically or in any other suitable way. For example, in some specific examples, the number of strokes may be programmed at the beginning based on the length of the tubular knitted fabric S to be processed. This can simplify the structure and control of the machine. This ends the reversal or reversal procedure.

若管狀針織物S尤其長，則其在反轉管15之第二向上衝程結束時可不被自反轉管15完全拉出。在此狀況下，上文結合圖7A、圖7B、圖8描述的相同步驟被重複一次或多次，直至整個管狀針織物S在反轉管15外部且較佳地在側開口15C下方為止。If the tubular knitted fabric S is particularly long, it may not be completely pulled out by the reversing tube 15 at the end of the second upward stroke of the reversing tube 15. In this situation, the same steps described above in conjunction with FIGS. 7A, 7B, and 8 are repeated one or more times until the entire tubular knitted fabric S is outside the reversing tube 15 and preferably below the side opening 15C.

在較佳具體實例中，反轉程序繼續，其中反轉管15重複往復移動，直至管狀針織物S脫離反轉管15之側開口15C為止，如圖8中所展示。In a preferred embodiment, the reversing process continues, in which the reversing tube 15 repeats the reciprocating movement until the tubular knitted fabric S leaves the side opening 15C of the reversing tube 15, as shown in FIG. 8.

圖10中展示下一步驟。降低上部抽吸管17（圖10中之箭頭f17），使得其下端17A被同軸地引入至反轉管15之上端15B中。The next step is shown in Figure 10. Lower the upper suction pipe 17 (arrow f17 in FIG. 10), so that its lower end 17A is coaxially introduced into the upper end 15B of the reversing pipe 15.

反轉管15現在可在其最底部位置中向後移動。此可能需要收回止動件16，若提供的話。圖11說明此新的狀況。抽吸管17之下端17A定位於拾取裝置5處或定位在該拾取裝置上方，反轉管15返回其下部位置，使得拾取裝置5之區域閒置，且可執行由拾取部件13接合之縫頭端的閉合。The reversing tube 15 can now be moved backwards in its bottommost position. This may require retracting the stop 16, if provided. Figure 11 illustrates this new situation. The lower end 17A of the suction tube 17 is positioned at or above the pick-up device 5, and the inverted tube 15 returns to its lower position, so that the area of the pick-up device 5 is idle, and the seam head end joined by the pick-up member 13 can be performed closure.

在本文中所揭示之具體實例中，藉由拾取裝置5與閉合機器7之共同起作用來執行縫頭端之閉合。然而，此情形並非強制性的。如所屬領域中已知，可使用額外裝置來執行縫頭端之縫合或連結，該額外裝置不同於拾取裝置5並且管狀針織物S一旦自針織機3移除，則其會被轉移至該額外裝置上。In the specific example disclosed herein, the closing of the seam head end is performed by the cooperation of the pickup device 5 and the closing machine 7. However, this situation is not mandatory. As known in the art, an additional device can be used to perform the stitching or joining of the seam end. This additional device is different from the pickup device 5 and once the tubular knitted fabric S is removed from the knitting machine 3, it will be transferred to the additional device. On the device.

在本文中所描述的具體實例中，一旦使拾取部件之兩個半圓形集合13A、13B處於重疊及面對面位置，則管狀針織物S之縫頭端藉由縫合或連結來閉合同時仍由拾取部件13接合。一旦閉合縫頭端，則使拾取部件之兩個半圓形集合13A、13B再次處於共面配置，同時自拾取部件13移除管狀針織物。In the specific example described herein, once the two semi-circular sets 13A, 13B of the picking member are placed in overlapping and facing positions, the seam end of the tubular knitted fabric S is closed by stitching or joining while still being picked up The parts 13 are joined. Once the seam head is closed, the two semicircular sets 13A, 13B of the pick-up part are again in a coplanar configuration, and the tubular knitted fabric is removed from the pick-up part 13 at the same time.

圖12展示已閉合縫頭端S1之步驟。縫頭部分位於抽吸管17之底端上。閉合的管狀針織物S接著經抽吸至抽吸管17中，如圖13中所展示。Figure 12 shows the steps of the closed seam end S1. The seam head part is located on the bottom end of the suction tube 17. The closed tubular knitted fabric S is then sucked into the suction tube 17 as shown in FIG. 13.

在上文所描述且附圖中所說明的具體實例中，單個拾取裝置用於：a）自針筒拾取管狀針織物，b）在反轉及閉合台中轉移管狀針織物，c）反轉管狀針織物，及d）閉合縫頭端。然而，在其他具體實例中，可預見管狀針織物之額外轉移步驟，使得例如第一裝置自針床移除管狀針織物，且第二裝置自第一裝置接收管狀針織物以執行剩餘的操作（反轉、閉合及移出）。在又其他具體實例中，第一裝置可用於自針床9拾取管狀針織物並反轉管狀針織物。該管狀針織物接著轉移至第二裝置，管狀針織物之端部在該第二裝置上閉合且具有閉合端之管狀針織物藉由抽吸管之抽吸自該第二裝置被移除。In the specific example described above and illustrated in the drawings, a single picking device is used to: a) pick up the tubular knitted fabric from the needle cylinder, b) transfer the tubular knitted fabric in the reversing and closing station, c) reversing the tubular Knitted fabric, and d) closed seam head end. However, in other specific examples, an additional transfer step of the tubular knitted fabric can be foreseen, such that, for example, the first device removes the tubular knitted fabric from the needle bed, and the second device receives the tubular knitted fabric from the first device to perform the remaining operations ( Reverse, close and remove). In still other specific examples, the first device can be used to pick up the tubular knitted fabric from the needle bed 9 and reverse the tubular knitted fabric. The tubular knitted fabric is then transferred to the second device, the end of the tubular knitted fabric is closed on the second device and the tubular knitted fabric with the closed end is removed from the second device by suction by the suction tube.
